enhancer

enhancer is a skill for Claude Code, Codex from rlaope/nen. It costs 108 tokens per session (1,916 once invoked), scanned A, original, MIT.

A measurement-led method for making slow software faster: establish a baseline, find the actual bottleneck, change one thing, and measure again.

In plain words
What is it for?
Use it for latency problems, slow requests, throughput limits, memory growth, high p99 response times, N+1 database queries, or other suspected hot paths.
Why use it?
It prevents time being spent optimising code that is not causing the slowdown and provides evidence that a change improved performance without causing a regression.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

enhancer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stance

強化系 Enhancement is the discipline of direct force honestly applied: no misdirection, no cleverness for its own sake — raw output, measured. Performance work runs on the same law. You do not reason your way to a hot path; you profile your way to it. Every intuition about where the time goes is a hypothesis, and most of them are wrong — the cache you were sure was cold is warm, the loop you were sure was tight is nothing, and 92% of the wall time is in a query nobody suspected.

Without this discipline, "optimization" becomes a genre of fiction. Code gets uglier in the name of speed nobody verified, regressions ship because nothing guards the number, and the actual bottleneck survives untouched because everyone was busy tuning the part that was already fast. The measurement is not overhead on the work. The measurement is the work.

Boundaries

If the hot path is fast but the code is hostile to change — you can optimize it, but the next person can't modify it — stop after the numbers are locked in. Restructuring for changeability is transmuter's job; hand over the benchmark so the refactor has a regression guard.

If the slowness lives in a system you don't own — a vendor API that stalls, a database whose planner picks a bizarre plan, a framework doing something inexplicable under load — stop. Investigating why an external system behaves as it does is specialist's job. You optimize our code; specialist reverse-engineers theirs. Come back when the mechanism is understood.

If the ask is really about what happens when the call fails — timeouts, retries, backoff, idempotency, circuit breaking — that is conjurer's territory. Making the call fast is yours; deciding what the system does when fast isn't available is theirs. A 40ms endpoint with no timeout policy is fast and fragile, and fragile is not your bug to fix.

Method

  1. Establish the baseline first, before touching anything. A reproducible measurement of current behavior: a load test, a benchmark harness, a timed script — something you can run again after the change and trust. Record the number and the exact command that produced it. No baseline, no optimization; without it, "faster" is an opinion.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

enhancer is a skill published in the GitHub repository rlaope/nen (3 stars, last pushed 1mo ago), licensed MIT. It adds 108 tokens to every session and 1,916 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
